The Minisforum MS-02 Ultra – The First 48 Hours

The MS-02 Ultra is the latest workstation from Minisforum, and is currently undergoing testing and review here at NASCompares. However, even after just 48 hours, a whole bunch of interesting design choices and unique qwerks to the arcitecture have emerged that I wanted to cover in the meantime before the full review is complete. The MS-02 Ultra essentially trying to recapture the magic and impact of the incredibly popular MS-01 – and it is attempting this by doubling, trippling and (in some cases) quadrupling the base specifications! The Minisforum MS-02 Ultra arrives as a compact workstation that incorporates a 24-core Intel Core Ultra 9 285HX processor, up to 256 GB of ECC DDR5 memory, internal 350 W power delivery, multiple PCIe expansion options, and a network configuration that includes dual 25GbE, 10GbE, and 2.5GbE. After 48 hours of initial testing, several hardware behaviors have emerged regarding thermals, acoustics, lane distribution, storage configuration, and chassis layout. The following sections outline these early observations, supported by confirmed specifications and hands-on inspection. Stay tuned for the full review, but at least for now, let’s discuss the early highlights and low lights!

Design of the MS-02 Ultra

The internal design of the MS-02 Ultra differs considerably from earlier Minisforum workstation models and moves away from the layout used in the MS-S1 Max. Although the system retains a slide-out internal frame, the mechanism is less streamlined than the earlier S-series implementation because of how densely the components are arranged.

The interior resembles a compressed micro-tower layout, with the CPU cooling assembly, PSU, PCIe risers, and storage positions layered closely together. A dual-fan ventilation chamber spans the frontal section of the chassis, pulling air through a vented intake and directing it across the primary cooling hardware before forcing it out the rear. This arrangement appears to be a necessary response to the higher thermal output of the Ultra 9 285HX and the inclusion of multiple expansion slots, both of which require more directed airflow than Minisforum’s previous compact workstation designs.

The placement of internal components reflects the limited spatial tolerance of the 4.8-liter enclosure. The internal 350 W PSU occupies a significant section of the lower frame and includes additional power leads intended for low-profile GPU or accelerator cards, something rarely present in machines of this size. The motherboard runs across most of the horizontal section and positions the CPU vapor-chamber cooler toward the middle, while memory slots, NVMe connectors, and the PCIe riser for the combo NIC occupy the remaining pockets of available space.

Because cooling pipes and the ventilation housing sit directly above the CPU-side memory slots, Minisforum added a custom angled heatsink to ensure airflow reaches these modules. This results in a serviceable layout but one that requires more deliberate disassembly, as the compact structure prioritizes component density and thermal guidance over ease of access or open internal spacing.

Early Heat, Noise and Power Use of the MS-02 Ultra

Initial thermal behavior suggests the MS-02 Ultra is managing its compact layout with a cooling strategy built around a dual-fan chamber and a six-heatpipe radiator assisted by phase-change material. During the first setup period, surface temperatures around the chassis varied, with readings near the side ventilation panels and case edges settling around the low-to-mid 40s, while the front intake area measured lower due to the direct airflow path.

Early internal temperature checks, taken before any sustained workloads were applied, showed values consistent with a system that is heavily packed but actively cooled across multiple zones. These readings align with Minisforum’s stated 5000 RPM maximum fan speed and the intention to maintain a 100 W to 140 W CPU power envelope depending on configuration. However, because these measurements were taken during routine preparation rather than stress testing, they provide only a preliminary indication of how the system will manage long-duration loads.

Noise levels during this early period ranged from the low 30s dBA while performing software installations and background operations, with no significant fluctuations unless brief bursts of activity occurred. This behavior suggests fan control may be tied primarily to BIOS-level thermal triggers rather than granular OS-side control, something that will require further testing.

Power consumption during light activity remained in the 50 to 60 W range, which is consistent with a workstation-class system running the Ultra 9 285HX while idle or handling moderate foreground tasks. Removing the dual-25GbE combo card or disabling its slot reduced power draw by roughly 10 to 11 W, highlighting the overhead associated with multi-lane NICs and onboard controllers. These early figures provide a baseline for comparison against heavier benchmarks that will be performed in the full review.

The 25GbE, 10GbE and WiFi 7 Network Card in the MS-02 Ultra

The MS-02 Ultra’s networking implementation is centered around a PCIe-based combo card that integrates dual 25GbE SFP+ ports with two additional M.2 NVMe slots. This card is installed in the PCIe 4.0 x16 position rather than the PCIe 5.0 slot, and it includes a dedicated controller with active cooling and heatsinks that cover both the networking and storage components.

Early inspection shows the card draws a notable amount of power, which corresponds with the increased thermal and electrical requirements of Intel’s E810-class 25GbE controllers. Because of this, Minisforum’s inclusion of dedicated airflow and structural reinforcement around the card is necessary within the constrained 4.8-liter chassis. The presence of this dual-purpose add-in card also means the MS-02 Ultra’s total NVMe count depends on whether the system is configured with the 285HX version, as the lower-tier CPUs remove the combo module entirely.

Beyond the 25GbE configuration, the system includes onboard 10GbE and 2.5GbE RJ45 ports, the latter supported by Intel’s i226-LM with vPro capabilities, allowing BIOS-level remote management. The combination of high-speed SFP+, copper-based multi-gigabit ports, and embedded management options positions the system for lab, server, or virtualization roles rather than conventional desktop use.

Wireless capability is supplied via a WiFi 7 and Bluetooth 5.4 module connected through an M.2 E-Key slot, providing high-throughput wireless performance alongside its wired interfaces. Together, these connectivity features expand the system’s potential use cases, particularly for users planning to deploy virtualized environments or bandwidth-intensive tasks such as shared storage testing or multi-system clustering.

How m.2 Storage on the MS-02 Ultra is Done

The MS-02 Ultra distributes its four NVMe slots across two different locations, with two mounted on the mainboard and two integrated into the dual-25GbE combo card. The pair located on the system board are positioned on the underside, near the memory and CPU assembly, and both are listed as PCIe 4.0 x4 according to Minisforum’s documentation.

Early inspection suggests that one of these may have a PCIe 5.0 lane path available at the hardware level, though software restrictions or lane bifurcation rules may currently limit it to Gen 4 behavior. This is an area that requires further validation using a Gen 5 SSD, as the lane layout on the 285HX platform allows various allocation possibilities depending on how Minisforum assigned bandwidth between CPU, chipset, and expansion slots. These internal slots have modest vertical clearance, meaning SSDs with tall heatsinks cannot be used without removing or replacing the pre-fitted cooling structures.

The remaining two NVMe slots reside on the network combo card alongside the 25GbE controllers. These operate under different bandwidth rules depending on SSD capacity: drives up to 4 TB operate at PCIe 4.0 x4, while larger 8 TB models shift down to PCIe 3.0 x4. This behavior appears to be related to the card’s onboard controller and how its internal bifurcation splits resources between the NIC and storage lanes.

Physical space is also restricted on the card, requiring low-profile SSDs in certain positions to avoid obstruction of the cooling shroud and airflow channel. Minisforum includes an additional heatsink in the package for users installing their own drives, but using SSDs with taller factory heatsinks may be impractical. Altogether, storage layout on the MS-02 Ultra is functional and high-capacity, but with lane behaviors and physical constraints that require attention during configuration.

Memory on the MS-02 Ultra

The MS-02 Ultra provides four DDR5 SODIMM slots, but their distribution within the chassis is unconventional due to the system’s compact thermal layout. Two slots sit on the mainboard near the CPU-side M.2 positions, placed directly in the airflow path of the vapor-chamber cooler and its dual-fan assembly. Because of this, Minisforum has added a custom angled heatsink that draws air from the primary cooling channel across the modules and nearby components.

This arrangement is intended to compensate for the thermal density around the CPU area, where heat buildup would otherwise be more likely. These two slots support both ECC and non-ECC memory, though ECC functionality is active only on the 285HX model. Their placement suggests Minisforum prioritized consistent airflow over ease of access, making upgrades possible but less straightforward than on more open workstation layouts.

The remaining pair of SODIMM slots is located on the opposite side of the board, positioned away from the CPU cooling assembly and closer to the chassis frame. These modules have more breathing room but rely on passive airflow from the system’s general ventilation rather than a focused cooling path. All four slots support speeds up to 4800 MHz, with XMP profiles unavailable due to Minisforum’s implementation and Intel’s platform limitations.

During early testing, memory installation worked as expected, though the arrangement of these slots means users planning maximum 256 GB configurations will need to work within the physical constraints of the layout. Overall, the memory design reflects a tradeoff between supporting high-capacity ECC configurations and fitting the necessary cooling infrastructure into a small volume.

PCIe Card Support on the MS-02 Ultra

The MS-02 Ultra incorporates three PCIe slots arranged to maximize flexibility within its compact chassis: a PCIe 5.0 x16 slot, a PCIe 4.0 x16 slot, and a PCIe 4.0 x4 slot. The PCIe 5.0 slot is left unoccupied by default, allowing users to install a low-profile GPU or accelerator card that fits within the airflow and power constraints of the 350 W internal PSU.

Minisforum includes auxiliary power cables within the system, which is uncommon for small-form-factor workstations and indicates that the chassis is intended to support cards that require supplemental power. Because of the chassis height and width, only dual-slot, low-profile cards with modest cooling requirements are viable, but this still introduces options for compute or media workloads that benefit from hardware acceleration.

The PCIe 4.0 x16 slot is occupied in the 285HX configuration by the dual-25GbE plus dual-M.2 combo card, which introduces additional thermal and power considerations. This leaves the PCIe 4.0 x4 slot available for further expansion, provided the card used meets the system’s spatial limitations. The layout demonstrates Minisforum’s approach to balancing lane allocation between CPU, storage, and networking, especially given the 24 available PCIe lanes on the Ultra 9 platform.

Although the physical presence of three slots in such a compact volume is unusual, the arrangement is functional, and power delivery from the internal PSU supports moderate add-in card configurations. Users will need to consider airflow direction, card length, and slot occupation carefully to avoid restricting internal ventilation.

Conclusion and Verdict on the Minisforum MS-02 Ultra (So Far…)

The MS-02 Ultra presents a compact workstation design that integrates a high-core-count CPU, multiple NVMe storage options, high-speed networking, and an internal PSU within a tightly arranged chassis. Early testing indicates that the system’s thermal behavior, noise profile, and power draw are consistent with its component density, though the long-term performance of its cooling strategy requires extended benchmarking before reaching definitive conclusions. The design choices, such as the split placement of memory slots, the use of a large dual-fan cooling chamber, and the reliance on a densely packed internal layout, all reflect Minisforum’s effort to fit workstation-grade hardware into a constrained volume.

In terms of features, the dual-25GbE plus dual-M.2 combo card remains the most distinctive element, expanding the system’s potential for virtualized environments, NAS roles, and bandwidth-heavy workflows. PCIe allocation, memory configuration, and storage behavior introduce several considerations for users planning upgrades or specialized deployments. While these early observations indicate a capable and flexible platform, further testing is necessary to determine sustained thermal performance, PCIe stability under load, and real-world throughput of the networking and storage subsystems. The forthcoming full review will provide those extended results, but for now, the system presents a feature-rich design with several areas that merit deeper evaluation.

Beelink Me Mini vs GMKTec G9 vs CWWK P6 SSD NAS Showdown

The compact and SSD-focused NAS landscape has grown increasingly competitive, with new models targeting users who require silent operation, efficient performance, and small-scale virtualization or media serving capabilities. Devices like the GMKTec G9, Beelink ME Mini, and CWWK P6 represent a distinct shift from traditional 3.5” HDD-based systems, instead favoring M.2 NVMe SSD storage in compact chassis designs. These systems are marketed toward home users, prosumers, and developers looking for a balance between cost, flexibility, and low-noise operation, often for roles such as Plex servers, UnRAID deployments, or containerized environments.

Each unit in this comparison leverages low-power Intel Twin Lake processors (notably the N150), offers at least dual 2.5GbE connectivity, and supports multiple M.2 drives, but their implementations vary widely in thermal handling, expandability, and internal architecture. As the line between DIY NAS builds and pre-built options continues to blur, the GMKTec G9, Beelink ME Mini, and CWWK P6 provide a snapshot of how different brands interpret the needs of modern users who prioritize energy efficiency, small footprints, and SSD-based storage workflows. This article evaluates these three devices across pricing, storage architecture, design, and real-world usability to provide a clear overview of their relative strengths and compromises.

CWWK P6 SSD NAS	Beelink ME Mini SSD NAS – HERE	GMKTec G9 SSD NAS

Beelink Me Mini vs GMKTec G9 vs CWWK P6 SSD NAS – Price and Value

The GMKTec G9 enters the market at around $199 for its 12GB RAM base configuration, positioning it as one of the more accessible SSD-based NAS units available. It includes a Windows 11 Pro license and Ubuntu Linux pre-installed, which can be attractive to users interested in general computing as well as NAS tasks. However, these operating systems are not tailored for storage-focused functionality, and the burden falls on the user to install and configure something like TrueNAS or UnRAID for proper NAS use. Additionally, the system uses non-upgradable LPDDR5 memory and features a plastic chassis, suggesting a design focus on affordability over long-term flexibility. While value is present in terms of included software and passive SSD-ready operation, its entry-level design limits appeal to users planning to scale or repurpose the device beyond its initial setup.

The Beelink ME Mini NAS, typically available at $209 on Beelink’s own storefront, offers a slightly higher upfront cost but balances that with integrated features aimed at simplifying deployment. Unlike the GMKTec G9, the ME Mini comes with an internal power supply and Crucial-branded SSDs in pre-built configurations, offering a greater level of assurance for storage reliability and plug-and-play readiness. The system supports Wi-Fi 6, Bluetooth 5.2, and features a silent fan-assisted cooling design that makes it more suitable for living rooms or office environments. Though it also utilizes soldered 12GB LPDDR5 memory, its form factor, passive aesthetics, and better thermals make it more appealing to users who want a quiet and tidy NAS solution that requires minimal tinkering post-installation. When compared to generic prebuilds, the ME Mini offers greater refinement and turnkey usability in exchange for a modest premium.

The CWWK P6 NAS sets itself apart with a lower base price of $195 for the N150 version, but this does not include memory or storage. Instead, the system is designed for users who prefer sourcing their own SO-DIMM DDR5 RAM and M.2 SSDs, potentially reducing costs if spare components are available. Its use of a single SO-DIMM slot enables expansion up to 48GB, which is considerably more than either the GMKTec or Beelink models. However, this flexibility comes at the cost of initial convenience. Users will need to handle their own OS installation, BIOS configuration, and possibly even resolve SATA recognition issues via firmware tweaks. The CWWK P6 also lacks wireless connectivity by default, and its use of a barrel connector rather than USB-C for power delivery may feel dated. Still, for users with a higher comfort level in DIY environments, the P6 offers a customizable platform with greater headroom for VMs, Plex, and containers.

When considering long-term value, each NAS appeals to a different kind of buyer. The GMKTec G9 is best suited for users who want a simple, functional NAS with minimal setup, though they may run into its limits quickly if performance expectations rise. The Beelink ME Mini justifies its price by offering a more thought-out design, silent thermals, and premium SSD options out of the box—better suited to users who want a clean and quiet system that can be set up rapidly. Meanwhile, the CWWK P6 represents a builder’s NAS: inexpensive upfront, highly scalable, and intended for users who value control over convenience. Ultimately, while price differences between these units are small, the total value depends heavily on user intent and whether ease of deployment, expansion, or component choice takes priority.

Beelink Me Mini vs GMKTec G9 vs CWWK P6 SSD NAS – Storage & Memory

All three NAS systems in this comparison rely exclusively on M.2 NVMe SSDs for internal storage, reflecting a growing emphasis on silent, high-speed flash-based configurations in compact enclosures. The GMKTec G9 features four M.2 NVMe slots, each limited to PCIe Gen 3 x2, offering a theoretical maximum of 2GB/s per drive. In contrast, the Beelink ME Mini supports six M.2 NVMe slots, with five operating at PCIe Gen 3 x1 and one—typically reserved for the OS—at Gen 3 x2. The CWWK P6 matches the G9 in having four slots, though each operates at PCIe Gen 3 x1 speeds, reducing peak bandwidth per drive. This difference in PCIe lane allocation directly impacts aggregate read/write performance, especially in RAID configurations or during high-traffic file operations.

The GMKTec G9’s storage slots are laid out beneath a plastic panel with no included heatsinks, a decision that raises concerns about sustained thermal performance. While it technically supports up to 32TB of total storage across its four bays, the lack of passive or active SSD cooling can lead to throttling unless third-party heatsinks are installed. The Beelink ME Mini, in contrast, integrates a large aluminum heatsink with pre-applied thermal pads on all six slots, ensuring consistent heat transfer and reduced risk of SSD overheating. Though five of its six slots are bandwidth-limited to Gen 3 x1, the thermal design makes it better suited for prolonged uptime and high-usage environments. The CWWK P6 also features a metal enclosure that acts as a passive heat sink, but ships with notably thin thermal pads and relies on an optional USB-powered fan for improved airflow.

Memory configuration is another key area of differentiation. The GMKTec G9 and Beelink ME Mini both ship with 12GB of soldered LPDDR5 memory running at 4800MHz. This fixed memory cannot be upgraded, limiting their long-term viability in RAM-intensive use cases such as virtualization or large-scale container deployment. The CWWK P6, by contrast, includes a single SO-DIMM slot that supports up to 32GB of DDR5 4800MHz memory, making it the most flexible of the three for VM hosting, ZFS-based NAS operating systems, or other memory-sensitive applications. The tradeoff is that buyers must provide their own RAM, adding to the setup cost but allowing for performance tuning based on workload.

Boot and operating system storage configurations differ subtly across the three units. The GMKTec G9 includes a 64GB eMMC drive with pre-installed Windows 11 Pro and Ubuntu, though the eMMC capacity is insufficient for most NAS deployments beyond initial setup. The Beelink ME Mini also offers a 64GB eMMC module but encourages users to install the OS on the Gen 3 x2 slot, especially in bundled configurations that include Crucial P3 SSDs. The CWWK P6 does not include any pre-installed OS or eMMC storage but does allow booting from any of its four NVMe slots, giving advanced users greater freedom to optimize OS installation, especially when using UnRAID or TrueNAS SCALE.

Ultimately, the memory and storage architecture of each system reflects different user priorities. The GMKTec G9 aims for simplicity but is hindered by non-upgradable memory and inadequate SSD cooling. The Beelink ME Mini offers better thermal management and storage capacity, albeit with limited PCIe bandwidth on most slots. The CWWK P6 provides the greatest upgrade potential with socketed RAM and M.2 flexibility, but demands user familiarity with thermal solutions, BIOS configuration, and peripheral sourcing.

The physical construction of these three NAS units reflects differing priorities in material choice, ventilation, and power integration. The GMKTec G9 uses a lightweight plastic chassis, which helps reduce cost but limits heat dissipation across its four M.2 SSDs. The unit relies on internal airflow generated by laptop-style fans, but its design lacks direct ventilation over the SSD bays, and the use of a plastic cover above the M.2 slots reduces thermal transfer. In contrast, the Beelink ME Mini is housed in a symmetrical 99mm³ cube with an internal aluminum heatsink and integrated fan. Its minimalist cube layout includes top and bottom ventilation for vertical airflow and maintains a more enclosed, consistent cooling environment that better suits SSD longevity in passive setups.

The CWWK P6 offers the most robust build quality of the three, using a solid aluminum alloy chassis that doubles as a passive heat sink. It includes a base-level fan mounted beneath the CPU and an optional USB-powered fan for SSD cooling. However, the included thermal pads are extremely thin, reducing their effectiveness under prolonged load unless replaced. Despite this, the chassis is designed to tolerate higher ambient temperatures and shows consistent performance in enclosed spaces. One drawback is the lack of airflow across the top panel unless the optional fan is mounted—without it, SSDs tend to accumulate heat more rapidly, especially during concurrent write operations or large file transfers.

Power delivery also differentiates these devices. The GMKTec G9 uses a USB-C power connector with an external 65W power brick, aligning with modern standards and reducing desktop clutter. The Beelink ME Mini further improves on this with a built-in PSU, removing the need for external adapters altogether and simplifying cable management in home setups. The CWWK P6 reverts to a more traditional 12V barrel connector, which, while functional, feels outdated compared to the USB-C or internal PSU solutions. This design choice may require users to carry a dedicated power supply, limiting flexibility in mobile deployments or environments with shared power infrastructure.

In testing, all three systems showed efficient power usage, though their idle and peak wattages differ slightly due to cooling, CPU behavior, and drive count. The GMKTec G9 drew 19–20W at idle and peaked at 28–30W under sustained load. The Beelink ME Mini demonstrated the lowest idle consumption at 6.9W with no drives, increasing to around 30W when fully populated with six SSDs under heavy activity. The CWWK P6 consumed approximately 18W at idle and peaked at 34–35W with three active VMs and four SSDs. These figures indicate that, despite modest differences in architecture, each system remains power-efficient and suitable for 24/7 use, especially in home environments with low thermal tolerance and energy cost sensitivity.

Beelink Me Mini vs GMKTec G9 vs CWWK P6 SSD NAS – Conclusion and Verdict

When assessed across all key metrics, the GMKTec G9, Beelink ME Mini, and CWWK P6 occupy distinct positions within the low-cost, all-flash NAS landscape, each catering to different user expectations and levels of technical comfort. The GMKTec G9 is the most turnkey in terms of initial usability, with pre-installed Windows and Ubuntu providing a base for users new to NAS setups or simply looking to use the device as a low-power desktop or file server. Its plastic chassis and lack of thermal optimization limit its suitability for intensive tasks, and the fixed 12GB LPDDR5 memory restricts performance scaling for containers or virtualization. That said, the G9 offers predictable behavior and basic capabilities that will satisfy those seeking an easy, entry-level NAS with minimal setup time, especially for local media streaming or light SMB file services. That said, the G9 is getting rather notorious for it’s poor cooling abilities – so much so that the brand has rolled out an improved cooling verion (see images below). There DO help, but the G9 is still the poorest of the three NAS in this comparison in terms of active cooling and long term temps!

The Beelink ME Mini, though only marginally more expensive, adopts a more premium approach to internal design and build quality. The integrated fan and large aluminum heatsink ensure more consistent SSD temperatures under sustained workloads, and the system is noticeably quieter at idle compared to the G9. Its six M.2 NVMe slots provide greater storage density potential, even though five are limited to PCIe Gen 3 x1 speeds. The soldered memory mirrors the G9’s limitations in upgradeability, but its inclusion of Wi-Fi 6, Bluetooth, and an internal PSU adds notable convenience for deployment in mixed-use environments like offices, bedrooms, or AV cabinets. It will appeal to users who value quiet, thermally reliable operation in a system that arrives largely preconfigured and ready for use with minimal additional hardware.

In contrast, the CWWK P6 forgoes polish and plug-and-play readiness in favor of maximum flexibility and user control. It is the only device in this group to feature upgradable RAM, allowing users to install up to 48GB of DDR5 memory, which opens the door to heavier workloads like virtual machines, ZFS-based NAS operating systems, or multiple Docker containers. The lack of included wireless, OS storage, or bundled RAM/SSD keeps the entry cost low but shifts responsibility onto the buyer to source compatible components. This extends to thermal management—while the chassis is solid aluminum, effective SSD cooling often requires replacing the thin stock pads and adding the optional USB-powered fan. These additional steps will deter less technical users but make the P6 a strong contender for builders, hobbyists, or professionals seeking a flexible platform they can adapt over time.

Ultimately, choosing between these three NAS units comes down to balancing ease of setup, long-term scalability, and thermal reliability. The GMKTec G9 suits users who want to get started quickly with a general-purpose device and accept limitations in memory and thermal design. The Beelink ME Mini delivers a more refined package, ideal for those who prioritize noise, storage density, and out-of-box functionality. The CWWK P6, meanwhile, is the most modular and scalable option, but requires technical confidence and additional investment in compatible components. Each has clear strengths and trade-offs, and the best choice depends on whether the user prioritizes convenience, passive reliability, or long-term upgradability in their NAS setup.

The Minisforum MS-02 Workstation – FINALLY A MS-01 KILLER?

Note – Massive thanks to PCWatch for their coverage of the Japan IT Week 2025 Event. They made an excellent article on the Minisforum MS-02 HERE and was the source for today’s article. Check them out!

The Minisforum MS-02 Ultra is a compact 4.8-liter workstation revealed at Japan IT Week Autumn 2025, marking a major upgrade over the earlier MS-01 model. Built around Intel’s 24-core Core Ultra 9 285HX processor, it merges high-end mobile CPU performance with features traditionally reserved for full-size desktops. The system includes support for up to 256 GB of ECC DDR5 memory, four PCIe 4.0 NVMe slots, and three PCIe expansion slots, one of which supports PCIe 5.0 ×16. Network connectivity options extend up to dual 25 GbE SFP28 ports, alongside 10 GbE and 2.5 GbE (vPro) Ethernet. Designed to serve as a workstation or mini-server, the MS-02 Ultra incorporates an internal 350 W Flex PSU, a slide-out chassis for maintenance, and advanced front-to-rear cooling architecture.

Minisforum MS-02 – Internal Hardware

The Minisforum MS-02 Ultra is built around Intel’s Arrow Lake-HX platform, with the Core Ultra 9 285HX serving as its central processor. This 24-core CPU combines eight performance cores and sixteen efficiency cores, reaching up to 5.5 GHz while maintaining a 140 W thermal design power. It incorporates an integrated Intel Arc GPU with four Xe cores and an NPU capable of up to 13 TOPS for AI acceleration. The CPU provides 24 PCIe lanes in total, which are distributed among the system’s multiple expansion and storage options.

Memory capacity is one of the most notable upgrades over its predecessor. The MS-02 Ultra offers four DDR5 SO-DIMM slots, supporting up to 256 GB of 4800 MHz memory, with full ECC functionality for stability in continuous workloads. Two modules are located on the CPU side of the board, and two on the reverse, optimizing thermal spacing and service access. This capacity places it closer to entry-level server configurations than typical mini PCs, reinforcing its suitability for virtualization or compute-heavy tasks.

Storage expansion is handled through four M.2 2280 NVMe slots, each supporting PCIe 4.0 ×4 bandwidth. Combined, these slots can accommodate up to 16 TB of SSD storage. The system’s slide-out chassis design allows quick installation or replacement of drives, simplifying maintenance. Minisforum has also introduced a small debug LED and clear CMOS button on the board, indicating that the model is targeted toward users familiar with system-level configuration and troubleshooting.

Expansion flexibility extends far beyond most small form factor workstations. The system includes three PCIe slots: one PCIe 5.0 ×16, one PCIe 4.0 ×16 (often occupied by a 25 GbE NIC in standard configurations), and one PCIe 4.0 ×4. The top slot can host dual-slot desktop graphics cards, drawing up to 140 W through an included 8-pin auxiliary connector. This allows for the addition of mid-range GPUs such as the NVIDIA RTX 4000 SFF Ada or workstation accelerators, while still retaining physical compactness.

Power delivery is managed through a built-in 350 W Flex PSU that eliminates the need for an external brick. This internal supply was a deliberate shift from the MS-01’s external adapter and helps sustain higher CPU and GPU draw without additional clutter. The unit supports 100–240 V AC input, giving it universal deployment flexibility for both workstation and light server scenarios.

 

Minisforum MS-02 – Ports and Connections

The Minisforum MS-02 Ultra includes a broad range of connectivity options intended to support both workstation and server workloads. Front access is optimized for frequent use, featuring two USB4 Version 2.0 Type-C ports offering 80 Gbps bandwidth each, a 10 Gbps USB Type-A port, a 3.5 mm audio combo jack, and the system power button. These front USB4 v2 ports also support DisplayPort Alternate Mode and Power Delivery up to 15 W per port, making them suitable for high-speed data transfer or direct monitor output without additional adapters.

The rear I/O layout is designed for permanent peripheral and network connections.

Minisforum MS-02 – Cooling and Temperature Management

The cooling system of the Minisforum MS-02 Ultra is designed to manage sustained high thermal loads while maintaining compact dimensions. The chassis follows a front-intake and rear-exhaust airflow pattern, similar to rackmount servers. A six-heatpipe radiator combined with phase-change material (PCM) ensures efficient heat dissipation from both the CPU and expansion slots. This design enables the system to maintain stable operation at a 140 W CPU TDP, even when fully populated with PCIe cards and NVMe storage. Airflow direction also varies depending on the unit’s orientation, with side-mounted intakes feeding the expansion slots and rear vents handling exhaust when the unit is placed horizontally or vertically.

The internal layout is structured to prevent thermal overlap between major components. The CPU and memory modules are cooled through a direct-contact heat spreader, while GPU and add-in cards draw intake air from the left side and expel it from the right or top, depending on placement. The inclusion of an internal 350 W Flex PSU was balanced with this design, ensuring sufficient clearance and airflow. This approach allows the MS-02 Ultra to sustain continuous high-load performance without external cooling solutions or the noise levels typical of larger tower workstations.

Minisforum MS-02 Ultra Workstation – Worth waiting for?

The Minisforum MS-02 Ultra represents a substantial progression from the original MS-01 workstation, addressing nearly every limitation of its predecessor. The earlier model, released in 2023, gained attention for integrating desktop-class performance into a small form factor but was constrained by its single-slot PCIe design, limited memory capacity, and reliance on an external power brick. The MS-02 Ultra resolves these issues with four DDR5 SO-DIMM slots supporting up to 256 GB ECC memory, a dual-slot PCIe 5.0 ×16 slot for graphics or accelerator cards, and a fully internal 350 W Flex PSU. These refinements, along with the addition of 25 GbE networking and USB4 v2 connectivity, elevate the system into a new category that bridges high-end workstation and compact enterprise server design.

Performance and versatility are at the center of this system’s concept. The inclusion of a 24-core Intel Core Ultra 9 285HX CPU and up to four PCIe 4.0 NVMe drives positions it for continuous workloads such as virtualization, software development, or AI inference without the thermal or structural compromises typical of small PCs. Minisforum’s decision to adopt ECC memory and RDMA-capable networking also underlines a shift toward reliability and professional usage scenarios rather than enthusiast or gaming audiences.

In terms of market placement, pricing has yet to be confirmed, but early indications suggest the MS-02 Ultra will likely start around $1,500, with higher configurations approaching or exceeding $2,000 depending on memory, storage, and NIC options. This aligns it with compact workstations like the ASRock DeskMeet X600 and high-end mini servers from OEM integrators, though the Minisforum model’s density and component flexibility set it apart. Overall, the MS-02 Ultra shows how far the brand’s SFF engineering has advanced since the MS-01, turning a well-liked prototype concept into a fully realized professional-grade workstation built for sustained heavy use.

The UniFi UPS-Tower 600W UPS Review

UPDATE – The Desktop UPS TOWER is available HERE for $159 , and the 2U Rackmount UPS-2U is available later in Q4 2025 HERE for $279

UniFi’s entry into the uninterruptible power supply market brings two distinct solutions tailored for professional and prosumer environments: the UPS-Tower desktop model and the UPS-2U Rackmount unit. The tower configuration provides 1,000VA / 600W of backup capacity and uses a single 12V, 9Ah lead-acid battery, while the larger 2U rackmount version scales up to 1,440VA / 1,000W with dual battery modules. Both adopt a line-interactive architecture with simulated sine wave output, a 6–10 ms transfer time, and Ethernet-based network management. Integration is handled natively within UniFi Network, where users can adopt, monitor, and configure the UPS directly from the UniFi Controller interface. For non-UniFi deployments, both models retain NUT (Network UPS Tools) compatibility for safe shutdown and system monitoring. This marks a significant expansion of UniFi’s ecosystem into power management and continuity—areas traditionally dominated by brands like APC and CyberPower—positioning UniFi’s UPS line as a bridge between smart network infrastructure and automated power protection.

The UniFi UPS-Tower 1000VA / 600W Review – Quick Conclusion

The UniFi UPS-Tower and UPS-2U deliver practical and ecosystem-focused power protection for small network environments. Both models emphasize integration and manageability rather than raw performance, providing stable 120V line-interactive backup power with simulated sine wave output. The tower model offers 600W of protection in a compact desktop enclosure, while the rackmount unit increases capacity to 1,000W with dual batteries. Integration through the UniFi Network Controller is straightforward, enabling central monitoring and alerting without external software. While limitations such as the lack of USB ports, PoE passthrough, and pure sine wave output restrict versatility outside the UniFi ecosystem, both units are solid entries for users seeking consistent, centrally managed backup power within UniFi-managed infrastructures.

The UniFi UPS-Tower UPS Review – Design & Connectivity

The UniFi UPS-Tower adopts a vertically oriented, compact chassis that measures 288 x 99 x 280.5 mm and weighs just over 8 kg. Its enclosure is built from a polycarbonate and ABS blend, which offers a balance between durability and low weight, and the overall shape resembles a small desktop speaker or heater.

The unit’s IP20 rating indicates it is intended for indoor use only, with ventilation panels positioned at the top, sides, and bottom to maintain airflow. During testing, internal temperatures averaged around 45–47°C after 24 hours of continuous operation, demonstrating stable thermal management for a unit of this density. The design is understated, with no LCD screen or physical display, relying instead on LED indicators and the UniFi interface for monitoring battery level and status.

In terms of connectivity, UniFi has implemented a clear division between power protection and control interfaces. On the rear panel, the UPS-Tower provides five surge-only outlets and five battery-backed surge-protected outlets, all of which are NEMA 5-15R ports suitable for 120V environments. The input connection uses a NEMA 5-15P plug, rated for 12A maximum load, supporting both 50 and 60 Hz operation. While this configuration is typical of compact line-interactive UPS units, the number of protected outlets is unusually high for its size, making it suitable for powering multiple small network devices, NAS units, or edge appliances simultaneously. However, only the five battery-backed ports will remain operational during a power loss.

UniFi has also included Ethernet management for remote monitoring and control. The rear I/O layout features a 100/10 MbE network connection that links the UPS directly into the UniFi ecosystem, as well as two GbE ports for surge in/out, allowing for protection of wired data paths. This implementation enables the UPS to send automatic notifications and power-state updates to the UniFi controller, ensuring that connected devices can safely power down when mains supply is interrupted. While users will not find USB connectivity here—a feature absent from both models—Ethernet management ensures seamless network-level integration with UniFi OS devices and provides remote monitoring capabilities not typically available in basic desktop UPS designs.

On the visual and operational interface side, UniFi relies on a multi-stage LED system to communicate battery and status information. A ring of LEDs on the front panel indicates power state, network connectivity, and battery percentage, with specific color patterns representing states such as initialization, adoption, or firmware upgrades. For example, a steady blue LED denotes normal operation, while flashing red signals a low battery, and alternating white/blue indicates firmware updating. This LED-centric approach aligns with UniFi’s existing product language and keeps the design minimalistic while relying on software integration for detailed telemetry.

Physically, the UPS-Tower fits neatly into a small office or studio environment, blending alongside UniFi routers or switches without dominating desk space. It operates quietly, with only a faint hum from the internal fan during battery mode. The 2U rackmount model, by contrast, uses a galvanized steel enclosure with front ventilation and nearly double the weight at 14 kg, prioritizing durability for data racks and wiring cabinets.

Both maintain an IP20 protection rating, ensuring basic safety against accidental contact but not dust or moisture resistance. Overall, UniFi’s approach emphasizes modularity, network integration, and compactness over display-driven functionality, positioning these UPS units as discreet but essential components within managed network setups.

The UniFi UPS-Tower UPS Review – Internal Hardware

Internally, the UniFi UPS-Tower follows a line-interactive architecture, combining voltage regulation with battery backup to ensure smooth transitions during power interruptions. The system utilizes an automatic voltage regulation (AVR) circuit that adjusts minor fluctuations in mains voltage without switching to battery mode, minimizing wear on the internal power cells. In the event of an outage or severe voltage dip, the UPS switches to battery operation within 6 to 10 milliseconds, maintaining output stability at 120V AC with a ±10% regulation margin. The waveform produced in battery mode is a simulated sine wave, which is adequate for most networking gear and consumer electronics, though not ideal for high-sensitivity audio, medical, or laboratory equipment. Power delivery remains consistent throughout short outages, allowing network hardware, NAS units, and servers to complete safe shutdown procedures.

The UPS-Tower contains a single 12V, 9Ah sealed lead-acid battery, user-removable via a bottom access panel. This design makes future maintenance straightforward, allowing owners to replace the battery when its capacity diminishes after several years of use. At full load (600W), the runtime averages around 2 minutes, while at half load, it extends to approximately 7 minutes before automatic shutdown. Recharge time to 90% capacity is listed at 6 to 8 hours. Thermal performance under sustained use is stable, and the inclusion of passive and active ventilation ensures no overheating under normal operating conditions. The system is also protected against short circuits, overloads, and over-voltage faults, automatically tripping into fault mode if thresholds of 110% to 120% load are exceeded.

Comparatively, the UPS-2U Rackmount uses a dual-battery setup with two 12V, 9Ah lead-acid modules to achieve 1,440VA / 1,000W output capacity. It shares the same waveform and transfer time but provides slightly extended runtime—2.3 minutes at full load and 8 minutes at half load—thanks to the added battery reserve. It also benefits from a galvanized steel chassis that enhances durability and is better suited for professional rack environments. Both systems are NDAA-compliant and certified under FCC, IC, UL 1778, and CSA C22.2 No. 107.3, ensuring safety and performance standards for commercial and residential use. In both models, system management and network telemetry are handled by a dedicated network controller chip, enabling UniFi OS integration and data synchronization with other UniFi devices.

The UniFi UPS-Tower UPS Review – Functionality

The UniFi UPS series is built around simplicity and ecosystem-level integration rather than feature-heavy configuration. Both the UPS-Tower and UPS-2U connect directly to the UniFi Network controller via Ethernet, where they appear alongside other UniFi devices for adoption. Once added, users can view real-time battery percentage, load level, input/output voltage, and system temperature directly from the UniFi interface. The units are also capable of sending power event notifications when mains power fails or returns, ensuring administrators receive alerts through the existing UniFi management system without relying on third-party monitoring software. This network-level approach allows the UPS to act as both a power backup and an automated coordination point for controlled shutdowns across UniFi infrastructure, such as Dream Machines, switches, or NAS units.

Integration with non-UniFi devices is handled through Network UPS Tools (NUT) compatibility. This makes the UPS-Tower particularly flexible in mixed environments where NAS devices or servers from other vendors, such as Synology or QNAP, require graceful shutdown when the UPS switches to battery mode. Users can define credentials and associate the UPS with NUT clients on the same network to relay status and trigger automated shutdowns once the battery reaches a predefined threshold. Although the review highlighted the lack of USB connectivity, which restricts plug-and-play use with devices expecting a traditional USB UPS handshake, the Ethernet management layer compensates by offering wider network-based communication. However, features such as per-device runtime configuration or selective port control are not yet implemented, leaving shutdown scheduling dependent on firmware updates or future model revisions.

The control and monitoring interface remains minimalistic, relying heavily on UniFi’s centralized GUI rather than onboard interaction. LEDs on the chassis provide a clear visual indication of status—covering power mode, adoption state, and battery level—but all deeper telemetry must be accessed through UniFi Network. Once paired, users can also configure email or push notifications for voltage irregularities, battery health alerts, and firmware updates. It is important to note that the current firmware does not support pure sine wave operation or lithium-ion battery upgrades, though UniFi has stated that future models will expand the portfolio to include these higher-end options. In its present form, the UPS-Tower and UPS-2U focus on stability, ease of deployment, and unified management within a single software environment, making them efficient for UniFi users seeking automation without added complexity.

The UniFi UPS-Tower UPS Review – Conclusion and Verdict

The UniFi UPS-Tower and UPS-2U represent the brand’s first foray into managed backup power systems, designed primarily to extend the reliability and consistency of the broader UniFi ecosystem. Both units share the same line-interactive architecture, simulated sine wave output, and Ethernet-based monitoring, offering a predictable and easily managed experience for users already invested in UniFi infrastructure. Their minimalist design, compact footprint, and seamless adoption through the UniFi Network Controller make them suitable for environments where simplicity, remote monitoring, and integration outweigh the need for advanced runtime management or pure sine wave output. For most small network or NAS setups, either model will provide adequate protection during short outages and brownouts, while ensuring systems are safely powered down when battery capacity is depleted.

However, their appeal remains closely tied to the UniFi ecosystem. The absence of USB connectivity, PoE passthrough, and lithium-ion battery options limits their usefulness in heterogeneous or high-performance environments. Users seeking pure sine wave support, longer runtimes, or advanced per-device control will likely need to wait for the next generation of UniFi UPS models, which the company has already suggested will expand to include these options. As they stand, the UPS-Tower and UPS-2U are well-built, tightly integrated, and cost-effective for UniFi users, but less compelling for those operating outside that ecosystem. They function precisely as intended: reliable, network-aware power backups for UniFi-managed systems, providing foundational stability rather than feature innovation.
